WebHowever, in the crystal structure of Cas9 bound to such a partial duplex, the HNH active site is not positioned close to the scissile phosphate (Figure 5c). One possible reason for this inactive conformation could be due to the lack of a 3′ end of sgRNA used for crystallization, which is critical for stabilizing the closed active state of ... WebOct 27, 2024 · However, Cas9 can bind and cleave partially complementary off-target sequences, which raises safety concerns for its use in clinical applications. Here, we report crystallographic structures of Cas9 bound to bona fide off-target substrates, revealing that off-target binding is enabled by a range of noncanonical base-pairing interactions within ...
